Double precision maths library

Dave Coxhill

Has anyone any idea where I can get a double precision maths library which will work with the Keil C51 compiler.

    "Yes - this one had me perplexed. 10 decades would be enough for me, but since the IEEE format calls for 8 bytes with a 53-bit mantissa (including the assumed leading 1) I don't know why ANSI C only calls for 10 decades."

    I don't think ANSI requires IEEE754 to be used. The explanation for the seemingly 'easy' requirements is most likely to avoid making old implementations non-conforming. ANSI have always seem to have adopted a policy of formalising existing popular implementations rather than pushing the boundaries forward.
